home theater system question

[David Legler]

so i'm looking at getting a home theater system for my room, my room isn't that big nothing large but i just want something better than the speakers on my tv. so i was looking at getting this one by Sony:

thought it seemed like a decent system for a decent price.

but then i saw some other discounted systems on best buy's website
and i saw something i didn't understand. they have a JVC 1000 watt system for $350 and right next to it is a 360 watt system by pioneer for almost $1000. maybe i'm just retarded but why is the 360 watt system so much more than the 1000 watt?

here's the links:

thanks for any help, i'm pretty much a noob when it comes to this so if anyone has any ideas, let me know. i'm looking at spending around $200
